Abstract

The phenomenon of reversible photobleaching in bacteriorhodopsin (BR) molecules exposed to 570 nm laser is presented. Creation of non-absorbing molecules in the bleached state is analysed theoretically using a simple theoretical model based on the excited-state absorption process. The analysis helps in ascertaining the percentage of molecules in the bleached state in the BR-based memory devices at any given time. The theory provides a bleaching parameter quantifying the number of photons the BR molecules can absorb before they reach a bleached state.
